To enable simple and correct finishing without failure when color-finishing a nail manicure, since coating a nail on the dominant hand becomes awkward willy-nilly and solution touches skin parts, and to enable finger movement by protecting the finished pretty nails to relieve the both hands otherwise in a stably fixed condition while drying after finishing.

A nail polish is coated on user's nails on revealed sections while covering skin sides by attaching nail-tools 1 to all the fingers of both hands, and safeguarding tools 2 are mounted on the nail-tools to protect the nails finished prettily. Leakage by over-dipping with the nail polish solution and invasion of bristle tips when rough coating are prevented by attaching a hard sponge plate of expanded polyethylene to each inside wall of the nail-tools as a defense wall 3. A spacing gap is formed by mounting a sponge plate of the same material on one end of the safeguarding tool as a safety wall 4 for keeping a spacing area between the both tools. The same one end is provided with a pair of stopper claws 5 so that the nail-tool does not easily slip out from the finger, thereby facilitating the finger movement by stable fixation.
